RT-32

The 32m precise parabolic antenna, designed (eng. Z.Bujakowski and his team) and built in Poland, is fully steerable classical Alt-Az mounted Cassegrain. It's main parabolic reflector is made of 336 panels, each with an accuracy better than 0.35 mm rms. The panels have been mounted and then adjusted to an accuracy better than 0.2 mm by classical laser based surveying technique. The final accuracy of the surface is therefore limited by the quality of individual panels. The construction of dish backing-structure is stiff and based on homological principle.
